Theresa McQueen: Calvin's killer talks...

After an almost six-month wait, the whodunit story came to an end this evening with the big reveal that Theresa was responsible for pulling the trigger on what should have been the (second) happiest day of Calvin and Carmel's life.

Here, in her first post-episode interview, actress Jorgie Porter explains how she felt on discovering the shock news, hints at what the future holds for Theresa and discusses the cast changes under new producer Paul Marquess.

What was your reaction when you discovered that Theresa was the murderer?"At first I thought, 'Oh my God'. It's a bit scary really because usually anyone who kills anyone in the show goes to prison for a very long time or dies themselves or never comes back!"

What happens in the aftermath of the shooting?"It's the whole guilt trip really. It was never planned because Theresa's not that type of person. She's not a murderer - she's a 17-year-old girl with little girl tendencies. She wants to talk about boys and clothes and make-up, then this comes along and totally changes her."

Does it make her grow up?"Well no, you see her become really vulnerable. You saw her vulnerable when her mum left but this is a total helplessness, she just doesn't know what to do."

Jacqui plays quite a heavy part in the aftermath, doesn't she?"She's really maternal towards Theresa. She's like, 'Right, this is what we've got to do', not because it's expected [of her] but Jacqui's been through prison. She's a hard nut, so Theresa would probably turn to her most out of anyone because she would know what to do."

How did the conversation go when you found out?"I was given my scripts and was reading them in the green room and was like, 'Oh my God!' When I got to the last page it was just unreal!"

You didn't cry, then?"No, I kind of didn't believe it really. Because it's a really good storyline for me it made me really happy. I always think that if I get a bit too giddy it will turn out to be too good to be true so I thought, 'OK, let's pretend it's not happening really and then fate won't take it away!'"

What was her motive?"Well, she'd recently had a night of naughtiness with Calvin, and as a result she fell pregnant. She was really stressed out about it and he's getting married so she thinks, 'If I go and tell him maybe he won't get married to her and maybe he'll want to bring up the baby with [me]'. I think she thought he would be with her."

Will this bring the family closer together?"There's a lot of anxiety about telling Carmel because Theresa can't really keep a secret. She wants to tell everyone. So she's going through life thinking she's on her own but she wants to tell people because it's the right thing to do but obviously Jacqui thinks this is a bad idea."

Theresa's obviously pregnant - are you ready for her to be a mother?"I think it would allow us to see a completely different side to her character, but I think she's probably a little too young."

Does she actually become a mum?"Well this is what I don't even know and I'd like to know, really! It could go either way, couldn't it?"

Are you wearing a prosthetic bump yet?"I'd love one - I don't have one yet but I'd love one and I'd love her to wear those belly tops like trendy mums!"

Would you be okay with working with a little baby?"Yes, I wouldn't mind chilling with a little baby. I just wouldn't know what to do with it! I think that would be acting! I like kids when they can walk and talk a bit but when they're little cradle babies I don't know what to do!"

Maybe they could flash forward by a few years for that?"It could be a teenager! But then I'd have to have a wrinkled face and make me into an old woman! That would be really cool actually…"

What's the atmosphere like on set now that Paul's in charge?"There are lots of new people coming in, so the green room's all very exciting! It's like things are brand new again and everyone's fresh and more exciting things are happening. When new people come in it's fresh for us as well."

You must be pleased that the McQueens are safe… "I'm so happy about that. Even if any of the other McQueens left I'd be gutted."

Are you excited about the new singings?"I've met Sheree [Murphy], and I've met Kim and the new Sharpe family. I walked into the changing room and Sheree had this summer dress on with her gorgeously stunning legs out - she was [looking] in her bag and I wolf-whistled and she turned round and I was like, 'Oh my God! I'm so sorry!' I thought it was one of the girls but it was Sheree and I was really embarrassed. She's got a good pair of legs, though!"

You're in Hollyoaks Later this year, too…"Am I? How many?"

Five apparently…"No way! I've not been told! I need to find this out - how do you find this out? Maybe I should read Digital Spy! Actually it's always upstairs on the computer to be honest!"

Now you know, are you excited?"I am - I absolutely love the late-night things. Usually when you get the scripts through they have to take a lot of things out because of compliance but with the late-nights they tend to stay in and it makes it more exciting and realistic."
